The invention Arelates I.to the 4manufacture of 'moldings suoli as are4used on,A automobile bodies fer concealing'thejoints between adi iacentpanelsand for'otheif purposes, and nthe 5 invention consists iny theconstructi'oiij by which the moldingstrips are fashioned in longitudinaly'aswell as cross-sectional ,con-i tour. l. L

In' the' `prese1it state of the art molding' 1U strips have beenformedby yadvancing a flat s'trip` v of metalfory other suitablematerial through aseries of forming rolls and guides, whichyprogressively change' the crossY SeC-v tional' contour.thereof.v 'Themoldings :de-'

` L, liveied from such machines are, however, ap-Y proximately straightand to,y change the lon"-` gitudinall contour must be subjected to ffurfther forming opeiations. f\7Vith vmyiinp-ioved machine the longitudinalfashioning may be accomplishedin vsequence to the cross sectionfashioning lsc that'the delivered moldiiigis ofthe desired forinin all of its dimensions.v

Adjacent to tl'e rolls E E there is mounted iipoiithe frame a stripdelivery nozzle H capable of universal angular movement in relation tosaid rolls.lfy As-shown this nozzle f comprises (a vstraight groovedguide'niembei' e L' which Vextends into the throat between the 60 rollsandwhich is mounted ona bearing block T pivoted'uponlthe shaft E2 of theroll E.

rovided means for var 7inn' pressure of the roll E on opposite edgeportions of the strip. Y This has the vei'lect of thinning' the gage ofmetal on one or the other side of theY strip, facilitating the bendingof the strip towards the opposite side. As shown this mechanismcomprises a cross bar P, which extends parallel to and above the lrollE. The bar is provided withl i,anis or 'Wedge portions P P2 at oppositeends thereof which pass between a stationary bearing' Q, on the frameand a vertically movable bearing Q in which' the shaft for the roll E isjournaled. R is an arm extending forwardfrom the bar .P having itsendattached'to a Vspring R, and being engaged intermediate its ends by atransversely movable bar S actuated by a cam S on the shaft of the VcamWheel M. The form ot the cani is such that duringreach'cycle the arm Ris moved the rod S to adjust the rod P iirst in one direction and thenin the reverse direction. This Will cause the cams P and P2 toalternately press down the bearings on the opposite end of the shaft forthe rolls P so as to increase the pressure first on one side and then onthe other. To adjust this pressure set screws Q3 are arranged to engageopposite ends ot the bearing Q so as to move the same in relation to theframe,

The mechanism that has been describedv is driven in properly timedVrelation by suitable gearing, not described in detail, so thatthecomplete operation. 'of the machine isas follows: When a dat strip ispassed between the rolls B, C, D, it Will be progressively changed incross-sectional contour as shown 4. to -9 inclusive. The steps,speelde-ally shown, are: 'first turning up' the edge' lianges; secon l.retnrnbendingthese and simultaneously bowing the inten ,i te'portion ofthe section; third. rollsai l, section to the desired curve; tourt.,placing a reverse curved groove in the con# ter or the strip; lift-h,puncturing the strip at intervals insai'd groove by .the points T Fromthe rolls D,DYthe on the l@ fashioned strip passes through lthestraightA guide Gg, which takes out any 'longitudinal curvature incidentto the forming action.

The strip thenpasses ,between the `rolls E, E, and into the nozzle H.This nozzle is moved through a predetermined path, swing-V kbothhorizontally in the plane of Vtravel of the strip andvertieally acordingto the larly movable nozzle H,-but better results are secured Where thisis combined lwith variable pressure of the roll E on opposite edgeportionso .the strip. rThis precludes any Wrinlding and imparts to theAfinished product a perfectly smooth contour.

The nozzle H preferably has its vertical pivotal axis in theplane ofContact between the rollsk E and E2; To permit ot this the block J isbifurcated'to embrace the roll E and the nozzle H is also slotted forthe passage of said roll. 'llhepivot K is thus formed by segments onopposite sides oi' this slot and the Walls of the slot are curved, asindicated at K. to permit the pro-per degree of angular movement. Thusthe strip, which is clamped along the line of contact between the rollsE and E and which is further guided by the groove in the' nozzle H, Willbe subjected to a, drawing act-ion during the angular movenient of thenozzle, which will give the desired curvature Without Vbuckling orWrinkling. Also, as has been already stated, the varying pressuresbetween the rolls E and E2 will thin the gage of the metal on the sideog' the strip which Vis being elongated.
